Deciding whether to buy in is actually quite straightforward—just do the math with specific numbers. Suppose this wave peaks at 12.6; what do you think are the chances it really drops to 8? Even if it does fall to 8, rebounding to 20 only yields a 1.5x return. Betting on such a large retracement risk for a 1.5x gain is simply not worth it.

Honestly, there are plenty of quality assets in the market, so there's no need to take this risk. The logic is so simple—since this round has already been well managed and you've successfully escaped the top, don't rush to buy until the price is sufficiently low. History tends to repeat itself: the last time it dropped from 6.9 to 4.8, we thought it was the bottom, but it ended up halving to 1.5. Many people got wiped out in this kind of repeated fluctuation.

Of course, if you have the mental resilience to accept that even if you buy at 9, you can calmly hold through a drop to 7 or even a breakdown to 5-6, then I wish you good luck. But the prerequisite is that you must clearly understand the maximum loss you can tolerate.
